This is an educational endeavor into learning a bit more about multithreading, messaging, and orchestration using C++20. Some goals, which will absolutely change as I experiement and mess around with it all:
- Orchestration of (synchronization between) threads should be be flexible, should be able to switch between synchronous, asynchronous + fixed rate synchronization, and purely asynchronous
- Messages sent between models should copy as little data as possible; make use of moves, pointers, etc.
- this is tough, how do you enforce copying underlying data when you need to persist it? e.g. a large object is sent via pointer and a receiver of the data holds onto that pointer. That data can change out from under the receiver, or potentially now the sender.
- Many-to-many messaging
- Messages carry provenance (minimally who sent it, when it was sent)
- Implement a thread-pool to allow for using a restricted number of resources (e.g. multithread 4 models across 2 threads)
- Top-to-bottom configurable via file (plan to use
nlohmann/json
)
Devcontainer provided; just launch a Codespace or local devcontainer!
This project uses Conan + CMake for dependency management and builds. You will need to install dependencies via Conan and then build via CMake (there are VSCode build tasks for these!):
# install dependencies
conan install . --build=missing
# load preset
cmake --preset conan-release
# build code
cmake --build --preset conan-release
Check out examples
for some basic usage. Need to script building these...
